Specification of Letters Patent.

Patented Mary 9, 1916.

Application filed November 12, 1915. Serial No. 61,080.

Toall whom it may concern:

Be it known that I, Esonas BELLEROSE, a citizen of the United States,residing at Watervliet. in the county of Albany and State of New York,have invented certain new and useful improvements in Vulcanizers, ofwhich the following is a specification.

This invention has for an object to provide a simple form of vulcanizingdevice such as is used for vulcanizing the outer casing of automobiletires while upon the wheel.

It is an important object of the invention to provide a constructionwherein a dry heat vulcanizer that is to say one that utilizes no liquidor other intermediate means for modifying the action of. the device maybe used without liability of burning the rubber.

An additional Object is to provide such a device having a chambertherein formed with an opening, having the double function of limitingthe quantity of fuel which may be placed in the device. and alsosupplying air to the gases arising from the fuel permit ting them torise readily from the lower part of the device, for combustionprincipally at a distance above the fuel, as will be made clear from thefollowing disclosure.

Another object is to provide a device which has neither a right norwrong end. and there will be no need for adjusting a particular endtoward the upper or lower side.

A further important aim is to provide a simple construction in suchdevices where ellicient combustion will be assured, while the heat isproperly modulated at the same, time.

Additional objects and advantages will appear from the followingdescription and from the drawings, in which Figure 1 is a view of thedevice in operative position upon a tire while engaged upon a wheel rim,Fig. "l is a horizontal sectional View, Fig. 3 is a vertical sectionalview of the device, Fig. 4 is a front view of another embodiment of thedevice, the shutter being omitted at one side.

There is illustrated a section of a wheel rim 10 upon which the ordinaryform of pneumatic tire shoe 11 is engaged, and applied thereto is avulcanizing device 12. con structed in accordance with my invention,

and comprising one of the possible embodinicnts thereof.

The vulcanizer comprises a. rectangular cast box having av concave backside 13, integral with which are the walls A by which the sides and endsof the box are inciosed, and over these walls in turn there is a frontplate 15. The space between the front plate and the back side is openfrom top to bottom within the box, and if desired a number of ribs orflanges 17 may be formed on the back side. the latter to take up heatgiven oil by combustion of fuel in the box. On the sides of the boxthere are formed lugs 18 having suitable openings therethrough in whichmay be engaged the customary bolts 19, having wing nuts 20 thereon, anda yoke or other suitable wheel engaging device 21 coengaged liietweenthe bolts.

In the front plate spaced a distance from each end of the box there areformed respective middle openings and s aced slightly a predetermineddistance beyond these openings farther from the respective ends of thebacl: and at each side, there are openings 23 approximately the samesize as the openings before ll'lfiflblOllQCl. The flanges l7 stop shortoi the respective ends of the box a distance, and at each end of the boXthere is introduced a suitable body of fibrous material fZ-l, such asasbestos.

in use, a suitable fuel is poured on the as tos at one end of the deviceuntil it reaches the level of the adjacent opening 22, and thereceptacle is then raised to a vertical position with the fuel at thelower part. The device being secured upon the tire in vertical positionas described, a match is then applied to the central opening, whichignites the fuel therein, the burning of which heats the back side ofthe box to a sufficient extent to vulcanize. the material which may havebeen placed upon the tire. The central opening serves to admit air forthe fuel which mixes with the gas and carries it upward a certaindistance, and the side openings serve to supply air to the gas afterhaving moved a distance above the fuel, so that combustion occursprincipally at a distance above the fuel, and prevents the developmentof gas at excessive rate. At ti upper end of the device the openin; iebeing spaced a distance below al opening serve to certain amount of gasthe es or bets-re combusnon, and before it has exerted its full heatinginfluence upon the upper part of the device, and this prevent-sexcessive heating at the upper end of the ap liance.

he important features of this invention consist in the relativearrangement of the central and lateral openings in the front plate. andI have discovered that by arranging these nearer the center of thedevice. the heat is decreased, while locating them nearer the ends givesan increase in the heating efficiency of the device.

In Fig. 4 there is illustrated a further development of this kind, inwhich the device is adapted to adjustment for variation of heatproducing capacity to meet the requirements of various seasons. As willbe readily understood. the device will be used out of doors, and in verycold weather a more rapid production of' heat will be required than inthe same situation on a warm summer day. In this case, the front plateis formed with longitudinal slots at each side extended a distance fromeach end. and on the outer side of the plate there are formed undercutflanges 25, between which there are slidablc shutters zfi. havingsuitable openings 27 therethrough for the purpose in view. Beside theflanges there may be formed in the plate a series of numbers as 20. i0,(30, 80, progressively from the outer ends of the slots toward thecenter of the device, in relation to which a small operating fingerpiece 28 may be formed, serving as a pointer.

' The figures have relation to the variation of atmospheric temperature,and indicate the proper positioning of the shutters for the variousheights of temperature indicated. Thus, when the temperature is low,

the shutter should be adjusted toward the outer end of the box wherebyan increased heating effect would be produced, whereas in warm weatherthe shutter should be moved in so that an excessive heat would not beinvolvedl The simplicity and cheapness of the device will be readilyapparent, and its efiiciency has been demonstrated by extensive use. Theform of the device may also be varied within the limits of theinvention.

An important advantage of the invention is that it provides a devicewhich. while having an inclosed flame and having means for containingliquid fuel, will not require the manipulation of any movable parts inintroducing the fuel or lighting the device, and the only movable partsconnected with the device or requiring manipulation regularly are thosefor clamping it upon the rim, or for clamping an article to bevulcanized thereagainst.

What is claimed:

1. vulcanizer of the class described cornprising a chambered body havingan apertured plate thereon. openings therein adjacent each end beingspaced a predetermined distance inwardly of the ends of the chamber forthe purpose described and openings laterally and inwardly thereofadjacent each end for the purposes described, and means for holding anarticle to be vulcanized.

2. vulcanizer of the class described comprising a chambered body havinga front plate formed with central openings for the purposes described,longitudinal slots laterally of the opening. sliding shutters over theslots and intermediate apertures therein.

In testimony whereof I have atlixed my signature in presence of twowitnesses.
